the 4.2L V-6 is already offerd for the '05 model.

 

I hope they go back to a pushrod design. Simple and compact.

 

Make the bore and stroke the same like the old 400 clevland. that was a troker engine, too.

 

yes they mention pushrod to compete with dodges new pushrod engine

 

Bite your tong!
On behalf of all V10 owners> you should not speak of such an injustice.
Unless Ford can figure out a way to get 362HP and 445 Ft Lbs out a smaller push rod motor that fires 2 less times per revolution which I seriously doubt with out a blower.
The V10 is quite fuel efficient. It takes a certain amount of gasoline to produce that kind of power. Piston diameter plays a big part of fuel efficiency.
I think the diesel would be the way to go. A turbo diesel V6 around 300ci should be capable of 300 hp and 425 ft lbs and 25 mpg in a F150.
I would buy one!

 

I think a turbo diesel straigt 6, around 300ci, would be better.

That said, I'd like to see ford bring back something like the FE. I DIDN'T JUST SAY BRING BACK THE FE!!! Just incorporate certain design elements, like over 4" bore, something over 3.5" stroke (3.784" would be nice...), deep skirt block, with a tall deck for good rod ratio. Let the cylinder heads, be they OHV or OHC, flow good, and put some good size valves in it. Basically make a big block. Call it the all new Ford 390. They'll sell like hotcakes!

 

I agree with the strait 6 but it just would not fit between the firewall and rad. If it would then the V10 would fit.
In 78 Ford offered a 460-C6 in a F150.
If Ford offered a V-10, Torque shift F150 SCREW I would own one.
I tow a lot of weight but don't haul much of nothin.

 

Yeah, what are we talking about little diesels for, gimme a 6.0 in an F-150, then we'll be talkin`!

 

Acually variable valve timing can be added to a pushrod design very easily and why do you want hight rpm capability in a truck anyway

Althought theoretically better fords ohc engines have been very down on power and fuel economy compaired to the competition

I find this humourus seeing how ford was thinking how they were going to blow the competition away with their 4.6 ohc back early in the 90's.

I personally beleive switching to ohc was more of an advertising gimic than anything, ford could say oh look we have an ohc that is more modern than a pushrod (most people being increadable ignorance will believe this) even though ohv and pushrod have both been around over 80 years.

 

The reason for the high revving truck motor is to allow for lower gearing. In the 50s, 60s and 70s trucks had 3 road gears and usually 4.10 or lower gears and small tires.
All that with a engine that had a 4500 rpm red line and a torque curve that started dropping off at 2200 rpm, and at 55 mph in top gear turning 3000 rpm. It has taken this long for the Big three to do their math and mate transmissions with more gears to engines that rev to match the lower gears.
The reason for OHC is besides making more power with less cubic inches is most of these Ford mod motors are good for 250,000+ miles without a rebuild, even being worked very hard.

lol you really think ford detuned them to so they had a long life span?

BTW most trucks didn't have 4.10's in the 70's it generally was a special order and on the 3/4 and 1 tons. Perhaps you should go work as an engineer seeing how you seem to think they are so slow and unless you have extremely short gears a high reving engine with a peaky powerband isn't' gonna work to well in a truck, what seems to be the most affective is to have a broad powerband

 

i'm a newb here. But, I would much rather have a very broad torque curve than peaky horsepower anyway. I don't want a truck to go fast, i want my truck to pull my fast car easily

I speak from experience when I say that mod motors ARE high reving motors and don't make much power till the upper rpms. I have a 1997 cobra that i race frequently. Its bored .020" over with a 3.75" stroke. a 4v 302 The torque curve is MUCH flatter than when it was just a 4.6 and you can feel the difference driving around town. However, it still doesn't make any horsepower till about 4,200 rpms. That's why i have a 4.30 gear and spin it to about 7500 rpms. I've thought about stepping up to a 4.88 gear, but unfortunely, I would have to run a very tall tire to pass the 1/4 mile mark in 4th and i don't want to tub the car.

Anyone been looking at the new Jeeps? Their redesigned 4.0L makes peak torque just above idle. When you have gobs of torque down low with a flat curve...your gonna get your payload moving much easier without the use of a steep gear. Also, the older windsor motors are very cheap to rebuild. That's why i like them. You can order a rebuild kit and have it delivered with your pizza - they are that abundant (thanks to the racing aftermarket). a 351 based 393 making 500ft/lbs of torque to the tire at 2600 rpms doesn't really need that much gear to get a good payload going.

 

I meant no injustice to the V-10. We owned a '99 and she was smooth and torquey as can be...but it got 12mpg on the highway doin 70mph with 2wd...the 6.2L Hurricane would easily surpass the V-10's 362horsepower....look at the new 6.1L hemi comming out...425hp...generaly yes it probibly would take more fuel for the smaller 6.2L to produce the same output...if they used the same basic design as the V-10. If they could some how come up with a super-efficient design then it's quite possible. Anyways i would not put it past Ford to decrease power levels just to satisfie more strict government regulations especialy with todays unstable fuel costs. On that note i also agrea more and smaller Diesel options would help out alot.

 

Connectingrod, I never said anything about Ford detuning and of their current OHC truck motors.
I also did not mean to imply that 5.4s or 6.8s don't have good low end torque. The stock 460s fell off so fast that at 50 mph with 3.73 or 4.10 it was a toss up weather to down shift or not when pulling a hill or passing. They were all ready revved beyond their torque curve. At least the newer OHCs keep on pulling up to 4500 rpm.
The japs built their reliability reputation on OHC engines. The push rod design is really old technology.
At this time Ford does not sell new vehicles in the US with a push rod motor and I will bet their not going back in the other direction.
Where I live here in the North West nothing but hills. To pull a 6% grade(which is most) at highway speed(60 mph) it works best to drop to the lowest gear you can(this multiplies torque) and still be in or near peak torque.
If the OHCs like to rev this allows for lower gears which allows for torque multiplication.
In the flat lands it is a different concept and I understand this.

 

Bronco did you not listen to a single thing I wrote lets try this again

push rod and ohc have been in existance a similar amount of time there for neither can be said to be "old tecnology" as you put it.

A 460 running out of breath before 4500rpm has little to do with the basic design and alot to do with the particular cyl heads cam etc that is in that engine. Many a push rod is capable of making power far above this rpm with out being terribly radical as gm and dodge have shown and even ford in the past. Trust me too when I say that a 70's ford 3/4 or 1 tone wasn't ment to travel at much above 60mph anyway which of course wasn't a problem before the days that it was fashonable to drive a truck instead of a car. Your comment about downshifting when you go up a hill...well you must be going up a pretty steep hill if you where thinking about down shifting a non od 4 speed stick. All this is no to suggest that ohc do not have advantages (which they do) but keep in mind pushrods have their strong points as well and to sell one off as being an old design is just ignorant
